kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

The vulnerability of the zram_bio_discard() function in the drivers/block/zram/zram_drv.c file of the Linux kernel’s compressed block device driver allows a hacker to cause a service failure.

The vulnerability of the zrambiodiscard function in the drivers/block/zram/zramdrv.c file of the Linux compressed block device driver module is related to the failure to release resources after their useful lifespan has ended. Exploiting this vulnerability could allow an attacker to cause a servi...
